<h3>Objective</h3>
Provide support to the Harvard Catalyst as they work to stand up XNAT throughout their user community.  Investigate the possibility that the Harvard Catalyst use case could be a model for additional CTSC sites that are also using the i2b2 framework, such as Emory University.

<h3>Approach, Plan</h3>
Specific open issues:
#Review data modeling requirement for XNAT from a MGH PI
#Contributing SubjectHandler Yong wrote into DicomServer release.
#Scan Level search capabilities for queries like "find all mr sessions with a usable MPRAGE scan". According to Tim, this is not an out-of-the-box thing offered by the REST API.
#Processing and loading images in NRRD format.

</div>

<div style="width: 40%; float: left;">

<h3>Progress</h3>
#Most of the data should have a close map to XNAT schema. Extensions to XNAT are needed to cover Testing session and Clinic Visit. XNAT will add a new field for "site".
#The SubjectHandler code was sent to Kevin Archie for consideration.
#This is now supported in xnat 1.4 rc3.
#NRRD files can be loaded just as any other files. New parser is needed to be written if it's is desired to get header information from the NRRD files.
